' LITTER AND COLLAPSIBLE FIELD-COT.

Specification of Letters Patent. Pat I nted Dec. 21, 1915.

Application filed February 19, 1915. Serial No. 9,236. i

To all whom it may concern: Be it known that I, ADoLFo ,LURIA, a min- Chicago, in the county of Cook and State 5 of Illinois, have -invented a certain new and useful Improvement in Litters and Collapsible Field-Cots, of which the following is a specification.-

: My present invention relates generally to" 10 litters-and Collapsible field cots. for army and domestic use, and more particularlv to improvements in the character of apparatus described and-claimed in my co-pending-application, Serial Number $375 which was.

filed February 5, 1915. More particularly the object of my present invention 'is to provide certain connections between the lateral braces of the frame.

and the legs, thereof utilized inthe cot formation, whereby the legs will be collapsed to positions adjacent and along the sidebars of the frame by the collapsing movements of the lateral braces when the formation. Fig. 2 is a view in side elevation of the litter. fEig. 3 is an end view thereof. Fig. 4: is a horizontal longitudinal sectional view therethrough. Fig. 5 is a cross sectional View through the litter. Fig. 6 is a view in end elevation showing. the litter folded. Fig. 7 is a bottom plan view of the litter with the parts in folded position;

Referring now to these-figures, the side 5 bars 1 of the litter each comprise tubular sections 2 and 3, of which the section 3telescopes into the section-'2 and the inner end wall of theinnersection 3 is formed with an opening 4, while the outer end wall of the section 2 is formed with an opening 5 Mining with the opening- 4, all as best seen in-Fig. 4.. Extending through these alined ipeni'ngs 4 and 5 is a rod 6 having one end /thereof fast within the opening 5 and the other end formed with a threaded nut 7 designed-to limit the'outward slidin movether movement.

ment of the section 3 with respect to the section 2. zen of the United States, and a resident of Formed on the section 2 of each of the side bars 1 adJacent to the outer end of such I section, is a pair of collars 8, the collars of each pair being spaced apart a suitable distance' Loosely surrounding each section 2, between the collars 8 thereon, is a sleeve 9, while fixed to the respective sections 3adacent to the. outer ends thereof are sleeves 10. Each of. the-sleeves 9 and 'lQ-isprovided with a lug 11 extending laterally and lnwardlv of the frame, and nivotallv cons nected at its outer end to the inner end of each ofthe lugs 11' is a lateralfbracing member or lever 12. The innerv ends-of the levers 12 of each pair are formed with late'rally projecting pivot 63.1S' 13 in superposed relation and through the ears 13 are passed vertical pivot bolts 14. The lugs '13 of each pair of the levers 12 arepreferably ofl'set as best seen in Fig. 3 so that the shoulders thus formed on the levers will engage in the operative position. Fig. 1', whereby the levers are rigidlyheld against fur- ,Rigidly connected to the pivot pins l5 extending vertically through the outer ends of the levers 12- and 11, are

- the upper horizontal-portions of rightj'an- 'gular brackets 16, while. carried bv the sleeves 9 and 10 are inwardly and downwardlv 'pro ecting'-right angular brackets 17. The depending or vertical portions of the bracketslfi and -17 are spaced apart in parallelism, and pivoted between the same are the upper extremities of legs 18, the lower ends of the legs 18 being formed with lateral project-ions constituting feet 19.

The upper end portion of each leg 18 is formed with a toothed segment 20 thatlower-ends of the meshes with a'similar segment 21 formed I on the adyaoentbuter'extremity of the respective lever 12. These'segments are disposed at right angles "to eachother'owing to the relative positions of the levers 12 and legs 18, and when the former are actuated to operative or extended position, the segments 2'1 meshing with'the' segments 20 swing the legs 18 ton vertical position so as to support the litter. above the ground for use as a cot, while when levers 12v ing of the cot, the segments 21: 'on the ends of the respective levers ll'and inxnesh with are actuated inwardly, incident to the foldges of the support'22 are equipped with oks:% that enga-gemopenings 25 in the enings 25' forming detachable connections portmay be folded onto the other half of 1 -:-the support when the litteris being folded or collapsed. The openings'25 in the sections3 adjacent to the inner ends thereof are preferably so positioned as to be disthe space between at23i T he remaining portions of the side levers n such position so that accidental closing of the litter is prevented. I

Succeeding the folding or collapsingof th rf e, as just described, the sections -2 '10" I of the side bars are revolved so as to take seeti'onse ofgthe, side bars, the hooks 24 and between the 'flexible'supportand the sections ,3 so that this "half of the 'fiexible'sup- I posed immediately adjacent to the inner ends of the sections 2 when the sections 3 1 l'gs ;depend.below the side bars to support.

'- the litterv and the hooks 24 engage in the openings 25', thereby enabling a person to be supported at full length above the ground. The outer ends ofthe side bars 1, that is, I the ends of the bars beyond-the sleeves 9 gi'a'nd 10, constitute handles whereby the litter or cotmay be'lifted and carried. about fromplace to place, when in use. To collapse the frame, the hooks 24 are disengaged from'the' openings 25 and this half of the canvas 22 'fold'ed onto the remaining half thereof se- .cured i to the side bar sections 2. 'The sec -ti ons 3 are now slid into the sections 2 to I see idi ninishthe length of, the frame and when the 1s done, the inner joints at 14 between the levers'12 are broken and the side-bars moved toward each other to reduce the,

I width o'fjthej frame. In-this latter movement of the side bars, the meshing segments "21,- 2-0,swing the legs to elevated position,- I and owing to the-positions of 'the lugs' 11, I the legs and bracketsliec within the plane of the side bars 1, so that any number of It will he noted that when t e parts are i in litter or cot formation, the inner connectedends of the levers 12 pass the line beas tween the pivotal connections of the levers folded litters, may be placed one. upon the other for shippmg'or' storage urposes.

prising sidebars, a canvas extending beup any slack inthe canvas 22 and provide I a comparatively small, compact article which may be readily and conveniently car ried about "on the back. I i

In the present instance, the lower face of the section of the canvas 22 that is fixed to the sections 2 of the side bars, is equipped with a pocket-26 designed to receive medi cine, surgical instruments, or analogousnecessary articles. I

From The foregoing descriptiontaken in connection with the accompanying drawings, the construction and manner 'ofas- ,s embling'mydmproved litter will be readily 3 5 l apparent, aswell as the advantages it provides over the several constructions described and claimedin my application above referred to.
